China's boosting e-commerce market is forecast to see sales volume of nearly 2 trillion U.S. dollars by 2025, said a report on digital megatrends released by FedEx Express.

China, the world's biggest e-commerce market, is embracing significant digitalization-related megatrends alongside its socio-economic growth, said the report.

ACCURATE ASTROMETRIC OBSERVATION

Chinese researchers have proposed a new method to precisely measure the astrometric positions of small near-Earth objects (NEOs), according to a recent research article published in the Astronomical Journal.

The precise astrometric observation of NEOs is valuable for research into the origin and evolution of the solar system, the detection and early warning of small NEOs, and deep-space navigation.
